Initial analysis

The O'Connor Family Trust owns this two-unit, two-story multi-family residential building located at 434-436 Noe Street, which was constructed in 1911 in the Eureka Valley/Dolores Heights neighborhood. The property has undergone significant improvements and modifications over recent years, with substantial work completed between 2017 and 2020. The most notable recent works include the installation of a comprehensive voluntary fire sprinkler system throughout the ground floor ($15,000) in 2018, followed by additional fire safety upgrades including a sprinkler monitoring system in 2020 ($4,000). The ground floor was converted into an ADU (Accessory Dwelling Unit) under Ordinance 162-16, with substantial improvements including ceiling height increase, new patio, concrete stairs, and lateral upgrades ($70,000) completed in 2019. Major building-wide upgrades were performed in 2017, including a complete remodel of both units' kitchens, bathrooms, and laundry facilities, along with electrical system improvements including removal of old knob and tube wiring and upgrading the main electrical panel from 60amps to 200amps.

The property has also seen significant infrastructure improvements, including new plumbing systems throughout both units, installation of radiant heating, and updated water service lines. Various plumbing and electrical permits from 2019 demonstrate comprehensive modernization of the building's systems. The building's external environment has experienced typical urban issues, with several 311 calls regarding street cleaning and encampment concerns between 2017 and 2021, though these cases were all resolved according to San Francisco's Department of Public Works and other agencies. The property's various permits and improvements suggest active management and regular maintenance of building systems, particularly focusing on safety upgrades and modernization of living spaces over the past five years.

Risk rating

How 434-436 Noe St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
